Abstract
The hub mechanism for wheel shaft includes the first hub disc, the second hub disc, flywheel fixed onto the first hub disc, axially expanding tubular hub neck set on the inner side of the second hub disc, and one fixing sleeve with one end jacketing the neck in tight fit and the other end jacketing the flywheel in tight fit. The fixing sleeve jacketing the neck strengthens the neck of the hub, and the hub neck has less deformation after the hub disc is tightened by the spokes. The present invention has simple manufacture process.
Description
Technical field
The present invention relates to a kind of car, particularly the hub mechanism of the wheel shaft of vehicle such as bicycle, three-wheel vehicle.
Background technology
The hub mechanism of axletree of the prior art as shown in Figures 1 and 2, comprise the first flower hub, the second flower hub, be fixed in the flywheel body on the described first flower hub, all along the circumferential direction have a plurality of spoke connecting bores on the described first flower hub, the second flower hub, the inboard of the described second flower hub is provided with axially extended tubular flower hub neck, and a tubular connection connects as one two colored hubs by riveted joint.Owing to need on the spoke connecting bore of two colored hubs spoke be installed, so spoke can make two colored hubs distortion after tension, then spends steel bowl and the steel ball in the steel bowl installed in the hub inner chamber can not cooperate well with spending hub, and is easy to wear when rotation.Because two colored hubs rely on tubular connection to connect, after therefore existing processing technology made them connect, the parallelism of two colored hubs was relatively poor, and working accuracy is difficult to guarantee, can causes taking turns axis deviation.The flywheel body and the first flower hub are to rely on the screw of spending the hub outer surface to pass screw, flywheel body is fixed on the outer surface of the first flower hub, because spoke can make colored hub distortion after tension, the flywheel axis hole that therefore is fixed in the flywheel body on the colored hub also skewness can occur.
Summary of the invention
The object of the present invention is to provide the hub mechanism of the axletree that a kind of processing and fabricating is simple, the right alignment of two colored hubs is good.
Technical scheme of the present invention is: a kind of hub mechanism of axletree, comprise the first flower hub, the second flower hub, be fixed in the flywheel body on the described first flower hub, the described first flower hub, all along the circumferential direction have a plurality of spoke connecting bores on the second flower hub, the inboard of the described second flower hub is provided with axially extended tubular flower hub neck, one end of a fixed cover is enclosed within on the described colored hub neck and interference fit captive joint with it, the other end of fixed cover is enclosed within on the flywheel body and interference fit captive joint with it, also is fixed with the first flower hub on the described flywheel body.
The present invention compared with prior art has following advantage:
Because fixed cover is enclosed within the colored hub neck on the second flower hub, therefore fixed cover can make the intensity of colored hub neck increase, and after the spoke tensioning on the flower hub, the distortion of flower hub neck is little, this structure makes that the diameter of flower hub can be less simultaneously, and the distortion of flower hub neck is little.Make by fixed cover in addition easily to guarantee to process the right alignment that latter two spends hub in two colored hub location that processing technology is simple.Fixed cover and flywheel body fuse by interference fit, and processing technology is simple.

Accompanying drawing 4 is a structure cutaway view of the present invention; Wherein:
1, axle bumper; 2, steel bowl; 3, spend the hub neck; 4, fixed cover; 5, flywheel body; 6, wheel shaft; 7, the first flower hub; 8, ball; 9, spoke connecting bore; 10, the second flower hub; 11, flywheel axis hole; 12, second internal end surface; 13, first internal end surface;
The specific embodiment
Referring to accompanying drawing 3 and accompanying drawing 4, a kind of hub mechanism of axletree, comprise the first flower hub 7, the second flower hub 10, be fixed in the flywheel body 5 on the described first flower hub 7, the described first flower hub 7, all along the circumferential direction have a plurality of spoke connecting bores 9 on the second flower hub 10, the inboard of the described second flower hub 10 is provided with axially extended tubular flower hub neck 3, one end of a fixed cover 4 is enclosed within on the described colored hub neck 3 and interference fit captive joint with it, the other end of fixed cover 4 is enclosed within on the flywheel body 5 and interference fit captive joint with it, also be fixed with the first flower hub 7 on the described flywheel body 5, its fixing mode is that the inner periphery of the described first flower hub 7 is enclosed within on the described flywheel body 5 and captive joint with it.
One end of described fixed cover 4 is set to the root of described colored hub neck 3, promptly spends hub neck 3 all to be inserted in the fixed cover 4, and described this root is the junction of the flower hub neck 3 and the second flower hub 10.
The two ends of described fixed cover 4 be against respectively second the flower hub 10 second internal end surface 12 on and first the flower hub 7 first internal end surface 13 on.
